The cushion case of the new Radiomir 1940 3 Days GMT Oro Rosso, 47 mm in diameter, is made entirely of 5nPt red gold, an alloy with a higher percentage of copper than usual and a small amount of platinum which helps to minimise the oxidation of the case. The polished red gold bezel surrounds the brown dial with a satiné soleil finish. The seconds hand rotates in the small counter at nine o’clock, while the arrow-shaped central hand can be used to indicate a second time zone, hence the engraved letters “GMT” at six o’clock.
The new Radiomir 1940 3 Days GMT Oro Rosso is powered by the Panerai P.3001/10 calibre hand-wound movement and is revealed through the sapphire crystal case back. It has a power reserve of three days as indicated on the back. The indicator is connected directly to the spring of one of the two barrels, both of which are skeletonised, as are the bridges with brushed finish. The movement also has the device for rapid setting of the hour hand, which can be moved forward or backwards in one-hour jumps of without interfering with the running of the seconds hand.
The Radiomir 1940 3 Days GMT Oro Rosso is water-resistant to 50 meters. The timepiece is mounted on a brown alligator strap secured by a red gold buckle.
